L vided in the bores of the sleeves 9 to engage the Adjacent the opposite end of spindle I is a locked in position by set screw 6. Around spindle I between the nut 5 and the collar 4 is a spring 1, normally Aurging collar 4 towards the'collar 2, for the purpose hereinafter described.

Around spindle I between the collars 2 and 4 is an annular series of blades 8, three being shown in Fig. 2. As shown more particularly in Figs. 2, 5, 6 and '7, the blades 8 are arcuate in collar 4 similar to collar 2, same having a conical cross section, the inner surfaces conforming in curvature to that of the spindle I, as Ashown in Fig. 2. On the under side of each bladef `at the center thereof are spacedy aligned inclined ribs 1 8a having their inner lower edges shaped to conform with the shape of the inclined grooves Ic in spindle I, the ribs 8a conforming in spacing and width to the grooves Ic, as shown in Fig. l. The ends of blades 8 are Voppositely beveled as at 8bV to conform with the conical recesses 2a and 4a of the collars 2 and 4, the conicalY rel cesses engaging the inclined ends 8b whereby the a series of shallow holes 8d in which suction is set up to assist in retaining the cylindrical flexible abrasive sleeve 9 Von the assembly of blades when placed thereon, the abrasive sleeve 9 being of length conforming with that of the blades 8. The holes 8d will serve, by suction, to maintain the abrasive cylinder 9 on the blades to prevent slippage orshifting during the honing operation.

By the above construction, when the nut 3 is roi tated relative to theA spindle I', `the collar2 will i b'e 'shiftedv towards the collar 4, which willyield under pressure of Vspring 'I and the series of blades 8 will be shifted axially of spindle I,

causing the inclined ribs 8a to ride upwardly in their inclined slots Iain the spindle whereby the diameter of thehone will be enlarged. 1

'The abrasive coated sleeves 9 may be made of any vsuitable material whose Vsurface is coated Ribs 9x (Fig. 10) may be progrooves 8c in the blades (Fig. 2) to prevent the sleeve from turning on the hone during operaprovides for greater accuracy since wear thereon is relatively even and the diameter of the hone willA remain substantially uniform. A' worn sleeve 9 may be quickly and easily replaced by a new one, thus making my hone economical vto use. The sleeves 9 are readily available in various diameters for use on the same hone when adjusted to corresponding diameters, and thus the hone is not limited to use with sleeves of only one diameter. Y Y

In Figs. 11, l2 and 13 a modification is shown in which the blades I0 as in the preceding figures have beveled ends and have the inclined ribs on their under sides. AIn this modification, however,

the outer face of each blade I0 is provided with a shallow v-shaped helical groove Illa throughout its length, the pitch being relatively small as indicated in Fig. 11, and the groove Illa preparing the surface of the blades II) for the cement which secures an arcuate-shaped stone hone II thereto, the assembly of stones II when the blades I0 are fully contracted around the spindle I: forming av substantially cylindrical surface,fas shown in Fig.-l3.

In Figs. 14, 15 and 16 a further modification is shown in which the blades I2 are generally similar to those in the preceding modifications with the exception that their outer surfaces are providedA with oppositely extending helical sha1- low V-shaped grooves IZa and I2b respectively, as's'hown in Fig. 14, adapted to prevent turning of the abrasive coated sleeve I3 mounted around the blades I2, the 'grooves I2a. and I2b replacing the holes 8d in the blade shown in Fig. '7 but serving the same purpose.

I do not limit my invention to the exact form shown in the drawings, for obviously changes may be made therein within the scope ofthe claims.

-I claim:

1*.,An adjustable hone, comprising a spindle l of substantially uniform cross-sectional size and shape throughout its length and having an annular series of spaced aligned grooves therein having theirbottoms inclined in the 'same direction anddisposed at the same angle to the axisjofthe spindle; and annular series of blades around the kspindle having their inner faces conforming'with the shape of the spindle,` each blade Ahaving a series of axially disposed aligned ribs on its inner face engaging the sides and bottoms of their related grooves, said ribs having their inner faces inclined in the same direction as and at the same angle as the bottoms of the grooves; said series of blades when in fully retracted position'forming a substantially cylindrical surface, means yieldably maintaining the blades 'positioned aroundr theV spindle While permitting the blades to besimultaneously shifted axially of the spindle to vary the diameter of the jhone' and abrasive member carried by the blades; said blades having helicalgrooves in their outer facesA of relatively small pitch; and said abrasive membercomprising stone hone sections adhesively secured to their respective blades and together forming a cylindrical abrasive surface when the blades are fully retracted.

2. An adjustable hone comprising a cylindrical spindle of substantialyuniforri size and having an annular series of spaced aligned grooves therein having their bottoms inclined in the same direction and disposed at the same angle to the axis of the spindle; an annular series of bladesV around the spindle having theirpinner and outer faces conforming withv the curvature of the spindle, each blade having a series of axially disposed aligned ribs on its under side engaging the sides and bottoms of their related grooves', said ribs having their inner faces inclined in the same direction as and at the same angle as the bottoms of the grooves; means yieldably maintaining the blades positioned around the spindle While per- `mitting the blades to be simultaneouslyshifted axially of the spindle to vary the diameter of 'the hone; an abrasive member carried by the blades; said blades having helical grooves in their outer faces of relatively small pitch; and saidl abrasive vmember comprising stone Yhone sections "adhesively secured to their'respective blades Aand f-.together forming a cylindricalabrasive surface when the blades are fully retracted. y :i j

3. An adjustable hone, comprising a spindle of substantially uniform cross-sectional size and shape throughout its length and having an annular series of spaced aligned grooves therein hav-- ing their bottoms inclined in the same direction and disposed at the same angle to the axis of the spindle; an annular series of blades around the spindle having their inner faces conforming with the shape of the spindle, each blade having a series of axially disposed aligned ribs on its inner face engaging the sides and bottoms of their related grooves, said ribs having their innerfaces inclined in the same direction as and at the same angle as the bottoms of the grooves; said series of blades when in fully retracted position forming a substantially cylindrical surface. means yieldably maintaining the blades positioned around the spindle while permitting the blades to be simultaneously shifted axially of the spindle to vary the diameter of the hone; an abrasive member carried by the blades; and said abrasive member comprising stone hone sections secured to their respective blades and together forming a cylindrical abrasive surface when the blades are fully retracted.
